BOBBIN.

SPECIFICATION forming part of Letters Patent N o. 602,260, dated April12, 1898. Application filed August 21,1897. sen-t1 No. 648,987. (Nomodel.)

To all whom it may concern:

Be it known that I, HENRY D. KLOTS, a citizen of the United States,residing at Garden City, in the county of Queens and State of New York,have invented a new and useful Improvement in Bobbins; and I do herebydeclare that the following is a full, clear, and exact description ofthe same.

My invention relates to bobbins for spinning, winding, and doubling silkand cotton, and is particularly directed to those having a wooden barrelor body and metallic heads or flanges, my object being to improve theconstruction of the metallic heads and their means of attachment tothebody.

The bobbin in which I embody my invention has a wooden core providedwith annular ribs near each end and metallic heads, each formed of twopieces of sheet metal bound together peripherally, surrounding the coreand bearing on opposite sides and the periphery of the said rib, so thatthe heads are light, stiff, strong, and rigidly secured to the body. Themetallic heads are likewise formed with bent integral prongs on theirinner edges, which are driven into the sides of the ribs to prevent theheads from turning on the core. I further form the metallic heads withannular recesses outside their ribbearings, in which recesses I fit theends of an outer barrel on which the silk or cotton is wound.

In order that my invention may be clearly ascertained, I shall firstdescribe in detail the mode in which I carry my invention into practice,and then point out its several features in the claims.

Reference is to be had by letter to the accompanying drawing,which formspart of this specification, and which is a sectional side view of abobbin embodying my invention.

A designates the wooden spindle-bearing core of my bobbin, which Iprefer to provide with integral or, as shown, rigidly-attached woodenheads 13, which I form with annular ribs 0, adjacent to their ends.

D designates the wooden outer or winding barrel of the bobbin, which ishere shown separate from the core A, but with which the core may beformed integrally or connected through the medium of an internal collaror disk in a manner well known to those skilled in this art.

1 form the heads E of the bobbin each of two pieces of sheet metal, aninner piece F and an outer piece G, bound together peripherally bypreference in the ordinary manner illustrated.

I fit the inner edges of the head-pieces F and G closely around therespective wooden head B of the core, so as to bear on the inner andouter sides, respectively, of the annular rib C, and I form onehead-piece, preferably, as in this case, the inner head-piece F,with acollar H to fit closely around the periphery of the rib O. The rib isthus tightly held between the collar H and the edges of the repieces Fand G, which is of course accomplished subsequently, makes a strong andrigid attachment of the metallic head to the core and a peculiarly stiffand strong head.

To insure against the heads turning on the core, I form the inner edgeof each, preferably outer metallic head-piece G, with integral prongs M,which are bent inward and driven into the wooden rib 0 around thecorehead B. In each inner head-piece F, I likewise form an annularrecess J outside the rib-bearings, in which the. respective end of theouter barrel is received and firmly held, and I by preference form theouter head-piece G with an annular recess K to accommodate the annularrib formed on the outer side of the inner head-piece by the recess J.

By this construction an extremely light,

strong, and serviceable bobbin is produced at a low cost.

I claim as my invention 1. A bobbin formed of a wooden core having fixedperipheral ribs, a short distance from each end,and metallic heads eachformed of an inner and an outer piece of sheet metal bound togetherperipherally, the inner edge of the outer head-piece encircling the coreand bearing axially against the outside of said rib, and the innerhead-piece bent axially to form a sleeve surrounding the periphery ofsaid rib and bent radiallyjto encircle the core and bear axially againstthe inside of said rib.

2. Abobbin formed of a wooden core having fixed peripheral ribs, a shortdistance from each end,and metallic heads each formed of an inner andouter piece of sheet metal bound together peripherally, the inner edgeof the outer head-piece bearing axially against the outside of said riband the inner headpiece bent radially to encircle the core and bearagainst the inside of said rib, then bent axially to form a sleevesurrounding the periphery of said rib and then bent outward radially andinward axially to form an annular recess around said sleeve, and anouter barrel having, its end seated in said recess and surrounding saidsleeve.

In testimony whereof I have hereunto set my hand the 1st day of July,1897.

HENRY D. KLOTS.
